Extra Cushioning for Comfort
Color: Red
This mat is thick and cushy - even with meniscus tears in both knees I can comfortably exercise. And I love the color.

Nice, thick & comfy but came w/ punctures in foam; seller provided discount
Color: Purple, Color: Purple
I love the mat. It's thick and very comfortable on my knees. However, when I opened it for the first time at my yoga class, there were several cuts or punctures in the foam. I attempted to return it and the seller offered me a 10% refund due to the damage. I am concerned that the mat may deteriorate due to the damage it came with, but I need it and have no idea if the cuts will matter over time. So I accepted the $3 refund and am keeping the mat.

Best mat purchase yet

I love this mat. I wish they had it in larger sizes. The only one I have truly non slip. Extremely comfortable especially on my back. Great price.

Great workout mat
Color: Green
It’s very thick and soft so it makes exercising a lot easier. It rolls easily ready to store. And it seems very durable. It is also flexible for certain exercises for balance.

Very sturdy. Great Quality
Color: Navy Blue
This is a very dense, thick mat. It's great if you have bad knees or just need/want a thicker mat. The carrying strap with velcro closures is easy to use.
